Based on the existing database access techniques,the distributed object CORBA (Common Object Request Broker Architecture) techniques are imported to construct the CORBA/Webbased database integrated architecture in the distributed computing network environment.
Analyzed that CSCW uses the requisition on database system systematically, CSCW and database integrate the systematic composition in the brief introduction, integrate the systematic development environment after putting forward CSCW and database.
' Based on analyzing some drawbacks of existing online monitoring systems and the evolution trend of remote diagnosis systems, an architecture of the distributed remote diagnosis system was presented using COR-BA specification. Some key technologies for implementing the remote diagnosis system were discussed such as POA strategies, Naming Service, Event Service, CORBA Component Model as well as Database Integrate. The fundamental function modules and implementation details of the diagnosis system for enterprise level and remote diagnosis centers were focus on.
According to the demand of one Container Enterprise of certain Port,this paper designs a Heterogenous Database Integrate System,which can utilize the existing information resources of this enterprise as fully as possible.
And analyzing the technology of dynamic web and web databases access, the ideas of realizing dispersed heterogeneous mold & die standard part library employed the technology of middle piece integration in scenario of federation databases integration.
In order to enhance rivalrousness of middle and small mold & dies enterprises' design and manufacture ability, based on the technology of web and databases integration and web show of graph, the purpose of this paper is to research on dispersed heterogeneous mold & dies standard part library based on web.
The underlying database integration process consist of three steps: first, the external database systems have to be connected to the integrated database system environment and the external data models have to be mapped into a canonical data model.
Schema implantation and semantic evolution, our approach to the metadata folding problem, is a partial database integration scheme in which remote and local (meta)data are integrated in a stepwise manner over time.
Instance-based attribute identification in database integration
Most research on attribute identification in database integration has focused on integrating attributes using schema and summary information derived from the attribute values.
The surface reconstruction algorithms have been demonstrated to provide accurate and smooth surfaces that are suitable for CAD database integration and CNC machine toolpath generation.
